[Chromecast] Improve rendering delay accuracy by tracking partial samples

The resampler can partially consume audio samples (since when resampling,
one output sample can correspond to fractional input samples). By keeping
track of the partially-consumed samples, we can improve the accuracy of
the estimated rendering delay.
